标题： A Correlation in the Waiting-time Distributions of Solar Flares

摘要： 在孤立的太阳活动区，我们发现，由GOES软X射线流量确定的耀斑强度与耀斑等待时间之间存在相关性。 “积累与释放”情景（BUR）对于太阳日冕中磁能储存提出了这种关系的存在，将缓慢变化的次光球能量源与耀斑和日冕物质抛射（CME）的日冕突然能量释放联系起来。 大量研究努力之前并未找到这种BUR过程的明显观测证据。 这引发了一个谜题，因为日冕磁场能量储存代表了基本耀斑机制的共识观点。 我们重新审视了两个孤立活动区的GOES软X射线耀斑统计数据，寻找任何相关性的证据，并发现了“饱和”相关性的显著证据。 而不是“重置”形式的这种弛豫，其中耀斑发生的时间 \textit{之前} 与其强度相关，“饱和”关系导致耀斑发生的时间 \textit{之后} 显示出相关性。 观测到的相关性与GOES灵敏度降低的效果相竞争，在这种情况下较弱事件可能会系统性地被低估报告。 这使观测到的相关性变得复杂，我们讨论了几种解决这一问题的方法。 显示英文摘要

摘要： In isolated solar active regions, we find that the waiting times between flares correlate with flare magnitudes as determined by the GOES soft X-ray fluxes. A "build-up and release" scenario (BUR) for magnetic energy storage in the solar corona suggests the existence of such a relationship, relating the slowly varying subphotospheric energy sources to the sudden coronal energy releases of flares and CMEs. Substantial amounts of research effort had not previously found any obvious observational evidence for such a BUR process. This has posed a puzzle since coronal magnetic energy storage represents the consensus view of the basic flare mechanism. We have revisited the GOES soft X-ray flare statistics for any evidence of correlations, using two isolated active regions, and have found significant evidence for a "saturation" correlation. Rather than a "reset" form of this relaxation, in which the time \textit{before} a flare correlates with its magnitude, the "saturation" relationship results in the time \textit{after} the flare showing the correlation. The observed correlation competes with the effect of reduced GOES sensitivity, in which weaker events can be under-reported systematically. This complicates the observed correlation, and we discuss several approaches to remedy this.
